Make kernel args the same in every config.
Put 'quiet' at the end of the line - it's usually the first thing a user removes when debugging.
Fill missing product versions in.
Distinguish between 'install' (installation media) and 'start' (live media).
In order for grub to be able to read the kernel regardless of whether
the image is written to a CD or a USB stick, it's necessary to autoprobe
for the filesystem using the findiso command. Add it to the grub config.
move arch-specific stuff to arch-specific subdirs and move all the
common stuff to a subdir named 'common'. Also, rename '.profile' and
'.bash_history' so you actually see them when you 'ls' the 'common' dir.
also added some helpful(?) comments to the templates.
